a–d Follow-up MRI study for same patient in Fig. 1. a, b sagittal T2 WIs, c, d axial T2 WIs, revealed better delineation of focal area of intermediate T2 signal seen involving the lower rectum (correlated to the same area found on the PET CT scan, 6–7 O’clock) and showing size progression as well, confirming the viable tumoral growth that was missed on the previous MRI due to the predominant fibrotic signal
